    perf tools: Drop unneeded bitmap_zero() calls · 3c8b8186
    Yury Norov authored
    bitmap_zero() is called after bitmap_alloc() in perf code. But
    bitmap_alloc() internally uses calloc() which guarantees that allocated
    area is zeroed. So following bitmap_zero is unneeded. Drop it.
    This happened because of confusing name for bitmap allocator. It
    should has name bitmap_zalloc instead of bitmap_alloc.
    This series:
    introduces a new API for bitmap allocations in kernel, and functions
    there are named correctly. Following patch propogates the API to tools,
    and fixes naming issue.
